Agrang is one of the great gods invoked in the Kherai, the central communal festival of Bathouism, in which the doudini (priestess-medium) dances the deeds of the deities before the sijou altar. He is characterised in the ethnographic literature as the general of the god-in-chief Bathoubwrai, leading the divine retinue, and in the systematised elemental theology of modern Bathouism he stands for water among the five constituent elements. He is regularly named together with Ailong and Khoila as the foremost attendants of the supreme god.
